Answer:

Step-by-step explanation:

We require to find DC

ΔDEC and ΔBAC are similar triangles, hence the ratios of corresponding sides are equal, that is

$\frac{ED}{AB}$ = $\frac{DC}{BC}$ , that is

$\frac{11.5}{23.5}$ = $\frac{DC}{44}$ ( cross- multiply )

23.5DC = 506 ( divide both sides by 23.5 )

DC ≈ 21.532

distance travelled = BC + DC = 44 + 21.532 ≈ 65.5 in → C

Sarah bought 5 items for a total of $24. A braceler

il63 [147K]

Sarah bought 3 bracelets and 2 pairs of sunglasses.

Step-by-step explanation:

Total items bought = 5 items

Total spent = $24

Cost of one bracelet = $5

Cost of pair of sunglasses = $4.50

Let,

x be the number of bracelet bought.

y be the number of sunglasses bought.

According to given statement;

x+y=5 Eqn 1

5x+4.50y=24 Eqn 2

Multiplying Eqn 1 by 5

$5(x+y=5)\\5x+5y=25\ \ \ Eqn\ 3$

Subtracting Eqn 2 from Eqn 3

$(5x+5y)-(5x+4.50y)=25-24\\5x+5y-5x-4.50y=1\\0.50y=1$

Dividing both sides by 0.50

$\frac{0.50y}{0.50}=\frac{1}{0.50}\\y=2$

Putting in Eqn 1

$x+2=5\\x=5-2\\x=3$

Sarah bought 3 bracelets and 2 pairs of sunglasses.
